cannot create activex component SQLxmlbulkload

Hi,
I'm just moving a new console program( created in visual basic 2010 express) from my PC to the server. Testing the compiled version on the PC is fine but on the server I get the message
Unhandled Exception: System.Exception: Cannot create ActiveX component.
the line in the program that it points to is

objbl = CreateObject("SQLxmlbulkload.SQLxmlbulkload")

I realise that when you create the program you need to add reference to Interop.SQLXMLBULKLOADLib.dll, which I did in the development region. However I did not see SQLXMLBULKLOADLib.dll appear in a bin directory, which is what happened when I created the program in asp.net.
Any suggestions to the issue. Could it be that I need to place a copy of Interop.SQLXMLBULKLOADLib.dll somewhere onto the server or do I put it into a bin directory in my VB project befor building. or is it something else.
Cheers in advance

createobject doesn't invoke the interop, it creates the com control directly.  You want to do something like:

SqlXmlBulkLoad.SQLxmlbulkload objbl = new SqlXmlBulkLoad.SQLxmlbulkload();

still though, it sounds like you don't have the com object installed on the server to begin with.  Search for "SQLxmlbulkload" in the registry, in HKEY_CLASSES_ROOT.  that will tell you if it's installed or not.

On your development machine, do the same.  there will be a key under it named 'CLSID".  take the default value (it will be a GUID) and search for it  (it will be in HKEY_CLASSES_ROOT\CLSID\).  In there will be a key named InprocServer32 with a value that shows what file it is pointing at.  The path might give you an idea of which software package the control is a part of.

glad to help.  All com/activex stuff is registered like that (regsrv32 just adds those registry keys).
